Pupils with Intellectual Disability (PwID) experience difficulties with acquisition of social skills. They find it difficult to initiate and maintain positive social relationships. Previous studies focused on enhancing academic skills of PwID with little emphasis on fostering functional skills. Therefore, this study determined the effects of Graphic Organizers (GO) strategy on acquisition of social skills among PwID. Three special schools were purposively selected. Twenty-six pupils that scored between 20 and 55 in the Screening test were adopted. Participants were randomly assigned to GOS (13) and control (13) for ten weeks. Slosson Intelligent Test (r=0.95) and Pupils Social Development Checklist (r=0.80) were used. Data were analyzed using Analysis of covariance and Scheffe post-hoc test at 0.05 level of significance. There was a significant main effect of treatment on acquisition of social skills (F=12.200, p<0.05, [eta-squared]=0.347). Participants in GOS group obtained the highest mean score (33.37) and control (27.40). Graphic organizers strategy fostered acquisition of social skills of PwID. Therefore, the strategy should be adopted in teaching PwID.
